Sweden's bid for NATO membership is facing a dead end because Ankara's demands to Stockholm to hand over Kurdish activists and prevent rallies attacking Turkey's leadership have strained ties.
The chances of this changing after Turkey's parliamentary elections due in mid-May are uncertain, said Paul Levin, director of Stockholm University's Institute for Turkish Studies.
"We can now probably forget Turkish ratification before the elections, which seem to be scheduled for May 14," Levin told AFP.
"What happens after that depends in part on who wins."
